Why Are There Black Streaks On My Roof?

Black streaks can be a very common issue with roofing. However, not many property owners understand the cause of it. People often mistake these streaks as a sign of aging, but streaks can begin to show no matter how old or new your roof is. If that’s the case, then what is the real culprit? The professionals at Roof Bear Tampa are here to tell you why there are black streaks on your roof and what you can do to treat or prevent them!

Introducing Gloeocapsa Magma: Your Roof’s Enemy

What is the black stuff that you’re seeing on your roof, exactly? Believe it or not, it’s a type of algae that’s growing and spreading across your roof. To be more precise, the algae that commonly affects people’s roofs are called Gloeocapsa magma. There are a few ways that Gloeocapsa magma spores can get onto your roof and grow:

  • Wind currents or wildlife can track spores onto the roof.
  • Leaves or branches can fall onto the roof and introduce spores.
  • Moisture retention with minimal sunlight can cause algae to develop and grow.
  • Damp and shady areas can create an optimal environment for algae growth.
  • Some types of asphalt shingles are more prone to algae development than premium-grade roofing materials.

What Happens When You Neglect Signs Of Algae?

If you decide to ignore the black streaks (or algae) on your roof, it can lead to worse problems and costly repairs. A roof that is already growing algae will most likely continue to spread them until it consumes the entire area. At that point, you may experience a significantly reduced lifespan for your roofing materials, some serious and hazardous structural damage, and decreased energy efficiency. The issue with energy efficiency comes from the fact that algae retain heat which can make your entire roof hot and affect your indoor temperatures. Failing to address algae for too long can put you at risk of voiding any warranties that could help you with the necessary repairs.

Ways To Prevent And Treat Black Streaks

The best way to fight against black streaks on your roof is to prevent algae from forming in the first place. Some ways to keep algae away is to make it so that your roof is inhospitable. Have your roof cleaned and maintained by professionals regularly and keep it dry with proper ventilation. Even trimming your trees to keep your roof exposed to the sunlight can be very effective. It also pays to invest in high-quality roofing materials that are made to be resistant to the effects of algae.

If you’re already experiencing black streaks, you can always call your trustworthy roofing specialists to clean your roof and remove any traces of algae. Depending on the severity of the status of your roof, it’s possible that you may need a complete re-roofing service to restore your property’s structural integrity and curb appeal. But whether you require simple roof maintenance or a re-roofing, where’s the best place to turn to in Florida?
